CKernelLocalTangentSpaceAlignment Class Reference

---

Detailed Description

the class LocalTangentSpaceAlignment used to preprocess data using kernel extension of the Local Tangent Space Alignment (LTSA) algorithm.

The stated eigenproblem is solved in the same way as CLocallyLinearEmbedding (LAPACK or ARPACK if available).

The local tangent space alignment step is parallel. Neighborhood determination is parallel as in CLocallyLinearEmbedding.

Please do not use multithreading whether your LAPACK is not thread-safe.
